Using Sandwich Pipe for Pipeline Vibration Control. Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage.

Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The project aims to develop direct applications for designing pipelines to suppress different sources of vibration and to guarantee the safety of pipelines.Read moreRead less

This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.Read moreRead less

A multi-scale theory of unsaturated porous media under extreme loading. Extreme loading induced by impacts, explosives or earthquakes generates stress wave propagation through unsaturated media; this can lead to rock fracturing and soil liquefaction and severely damage civil, mining and military infrastructures and operations.

Extreme loading induced by impacts, explosives or earthquakes generates stress wave propagation through unsaturated media; this can lead to rock fracturing and soil liquefaction and severely damage civil, mining and military infrastructures and operations. The project aims to develop a novel experimentally-validated theory, with associated models, for describing dynamic responses of unsaturated porous media subject to extreme loading. Our continuum framework will allow building constitutive models directly from saturation-dependent contact laws at the micro-scale. This will remove the need to use the site-dependent empirical models and thus give the derived constitutive models truly predictive capabilities.Read moreRead less
